Hey Mr Lert, if you're thinking of abandoning noise abatement for the sake of operational efficiencies to the airlines, then I think you've picked a pretty weak example. Your suggestion helps about half a dozen flights a day. And that's only on the days where 34 is in use for departures!
How about trying to fix the situation where
every single arrival for several hours a day cops up to a fifteen minute airborne delay, just for the privelege of landing on a less safe, noise sharing runway (usually with excessive cross and/or downwind)? Good luck!
